So why do you want to obfuscate glabel with it? For people to start depend on it? Once we start supporting 4kB sectors what do we do with such a change? Remove it and decrease version number? What people will do with providers already labeled this way? If its temporary, just allow to list providers you want to increase sector size in /boot/loader.conf. Once we start supporting it properly people might simply remove it from loader.conf and it should just work. Glabel is not for that and I don't agree for such obfuscation. --=20 Pawel Jakub Dawidek http://www.wheelsystems.com pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
